debian and ubunu, how to make ubuntus grub roll over

#1 Post by metalfan »

hi,


system looks like this:
encrypted lvm
some partitions for debian
one partition for ubuntu
both share the same boot partition

for hardware(skylake) testing purposes i installed a ubuntu next to my existing debian jessie, both boot.
now i updated the ubuntu kernel to 4.5.0...lowlatency..., with dpkg -i *.deb (kernel-headers and kernel-image in the local directory)

after that gub associated that kernel with my debian installation which resulted in it not being able to boot.
couldnt find "root", maybe that kernel is not made for booting a system on a encrypted lvm.

easy fix: edit the boot menu.

i just did run "update-grub" from debian, looks like it associates the first kernel (alpabetical) which is the 4.5.0-040500-lowlatency with the first operating system.

how do you handle this situation?

basically i need debian to boot: linux-image-4.5.0-debian
for now im gonna remove the lowlatency kernel and boot ubuntu with the debian one
